The left end consisted of electromechanical computing components. The right end included data and program readers, and automatic typewriters. The Harvard Mark I, or IBM Automatic Sequence Controlled Calculator (ASCC), was one of the earliest general-purpose electromechanical computers used in the war effort during the last part of World War II.
ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3 ] [ 4 ] Other computers had some of these features, but ENIAC was the first to have them all.
A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters , which use the turning of gears to increment output displays.
The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. [3] The Z3 was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. [1] Program code was stored on ...
Replica of Zuse's Z3, the first fully automatic, digital (electromechanical) computer. In 1941, Zuse followed his earlier machine up with the Z3, [71] the world's first working electromechanical programmable, fully automatic digital computer. [74]
Howard Aiken married three times: to Louise Mancill in June 1937, then later to Agnes Montgomery, and lastly to Mary McFarland. He had two children; one with his first wife, and one with his second. [10] Howard Aiken was also a Commander in the United States Navy Reserve. [5]
Konrad Zuse designed and built electromechanical logic gates for his computer Z1 (from 1935 to 1938). The first recorded idea of using digital electronics for computing was the 1931 paper "The Use of Thyratrons for High Speed Automatic Counting of Physical Phenomena" by C. E. Wynn-Williams. [29]
